On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal

open access: yesChemie Ingenieur Technik, EarlyView.
Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

An accessible microfluidic perfusion platform for time‐restricted control of zebrafish embryonic patterning

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Understanding the dynamic nature of developmental networks requires live imaging techniques capable of capturing real‐time developmental processes in wild‐type and mutant embryos as they are exposed to pharmacological perturbations. A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of ...

A Critical Review of Electrolytes for Sodium‐Zinc Hybrid Ion Batteries: From Liquid to Solid

open access: yesEcoEnergy, EarlyView.
This review systematically discusses the evolutionary roadmap of electrolytes from liquid to quasi‐solid and ultimately to all‐solid‐state structures for aqueous sodium‐zinc hybrid ion batteries (ASZIBs), which focuses the critical bottlenecks of uncontrolled dual‐ion transport and interfacial incompatibility, and proposes corresponding countermeasures
